Peter Pettersson har samlat några tvärsäkra påståenden om "gasattacken i Douma". OPCW börjar sin undersökning idag.The U.S. State Department spokesperson Heather Nauert said Friday there was a "very high-level of confidence" that Syria was behind the attack, but did not elaborate on what type of evidence the department has."We believe we know who was responsible for this. We will still wait -- the Organisation for the Prohibition of Chemical Weapons (OPCW) will still formulate its facts and its findings, but it does not determine the responsibility, they determine the substance," Nauert said Friday.https://www.cbsnews.com/news/chemical-gas-attack-syria-confirmed-by-state-department-2018-04-13/

The Syrian regime used barrel bombs dropped by helicopter in a chemical weapon attack on its own people in the city of Douma, according to the US, France and Britain yesterday.“Numerous eyewitnesses corroborate that barrel bombs were dropped from these helicopters, a tactic used to target civilians indiscriminately throughout the war. Photos of barrel bombs dropped in Douma closely match those used previously by the regime. These barrel bombs were likely used in the chemical attack.”"Open source accounts allege that a barrel bomb was used to deliver the chemicals. Multiple open source reports claim that a Regime helicopter was observed above the city of Douma on the evening of 7th April."Reliable intelligence indicates that Syrian military officials co-ordinated what appears to be the use of chlorine in Douma on 7th April."https://www.telegraph.co.uk/news/2018/04/14/evidence-shows-syria-attacked-people-chemical-weapons-say-us/
